3）工程参数设置
工程参数设置如下图所示，其中相机文件需要手动选择刚导出PATB_HTYJ文件夹下的，扫描分辨率需要手动输入毫米单位的像元大小/扫描分辨率（mm_width/pixel_width）。注意：尤其是导入cam文件后会再次自动变为默认值。

4）工程数据确认
升序排列或者将序排列一下后确定。
![](https://wkrtcs.bdimg.com/rtcs/image?w=302.40&md5sum=5e582492d5881147e145a320ae96e259&sign=9902dad24a&rtcs_flag=2&rtcs_ver=4&l=webapp&bucketNum=322&ipr={"t":"img","r":"r_22","w":"302.40","h":"377.60","dataType":"png","c":"word/media/image8.png","imgOriW":378,"imgOriH":472})
5）创建立体像对
在PATB上点右键选择创建立体像对。
![](https://wkrtcs.bdimg.com/rtcs/image?w=183.18&md5sum=5e582492d5881147e145a320ae96e259&sign=9902dad24a&rtcs_flag=2&rtcs_ver=4&l=webapp&bucketNum=322&ipr={"t":"img","r":"r_22","w":"183.18","h":"515.14","dataType":"png","c":"word/media/image9.png","imgOriW":229,"imgOriH":644})
6）修改核线类型为大地
选择立体像对，在右侧修改核线类型为大地。
![](https://wkrtcs.bdimg.com/rtcs/image?w=423.15&md5sum=5e582492d5881147e145a320ae96e259&sign=9902dad24a&rtcs_flag=2&rtcs_ver=4&l=webapp&bucketNum=322&ipr={"t":"img","r":"r_22","w":"423.15","h":"171.62","dataType":"png","c":"word/media/image10.png","imgOriW":1058,"imgOriH":429})
7）核线重采样（可选）
选择需要重采样的立体像对，右键选择核线重采样。如果不进行该步骤，则在DLG中用实时核线查看立体，所以是可选步骤。
另外，在实际生产中也遇到实时核线视差大但是生成核线影像就不存在视差大的问题。
